RENOVATION OF KANGO BRIDGE Case study: GABON, ESTUAIRE PROVINCE – KANGO SECTOR

Abstract

The Kango Bridge, an essential infrastructure for local and regional transportation, has suffered significant deterioration over the years due to aging materials and environmental conditions. This study addresses the urgent need for its renovation, emphasizing the use of reinforced concrete techniques to ensure long-term durability and safety. The problem statement focuses on the structural weaknesses observed in the bridge, including cracks, corrosion of steel reinforcements, and reduced load-bearing capacity, which pose significant risks to users. The main objective of this study is to propose an efficient and cost-effective renovation plan for the bridge, ensuring compliance with modern engineering standards and extending its service life. To achieve this, a comprehensive assessment of the existing structure was conducted, including material testing and structural analysis. The methods involved non destructive testing techniques, load capacity calculations, and design simulations for the proposed reinforcement strategy. The results demonstrated that H = H1−H2=0.6 m and a constant K= 100. This relationship indicates that for every meter of height difference, the span increases by 100 meters., combined with improved drainage and protection measures, would significantly enhance the bridge's performance. In conclusion, the proposed renovation plan addresses the critical issues faced by the Kango Bridge and offers a sustainable solution to prevent future deterioration. Recommendations include regular maintenance schedules, continuous monitoring, and further research into innovative materials for infrastructure projects.
